Integrated AC servo motors gain WLAN module
JVL is well known for its very wide range of modular integrated AC servo motors, and now the company is introducing the facility to connect an integrated MAC motor to an existing Ethernet using a newly developed WLAN-module, providing access to set-up and control the motor from anywhere on the network. Moreover, with appropriate IT-infrastructure, it is possible to access the motors via the internet using fixed IP addresses or via a VPN.
This new module provides completely new opportunities for remote control, monitoring and diagnosis, thereby enabling the motors to be used in distant locations where service would otherwise require considerable transport.
For shorter distances or local use, the WLAN-module means that cabling can be avoided. Software can be used to connect a PC to the motor as if it were connected via a serial RS-232 cable.
This WLAN module is also useful for applications where the motor is mounted on a moving sub-assembly - such as an indexing table - and is powered via a slip-ring. Another typical application is where control signals are supplied from a handheld, battery-operated unit.
It is possible to use a wide range of the most recent encryption standards.
Programming software
Like the well-known JVL RxP nano-PLC module, the MAC00-EW4 WLAN module is programmable so that small PLC programs can be executed directly in the motor. JVL's MacTalk software with graphical interface (for setting parameters and programming) is identical to that used for the RxP-module, and programs can be directly transferred between the RxP, BlueTooth and WLAN modules, taking the use of I/O signals into account.
Connection of the supply and signals is done via three robust M12 connectors. The Module has a standard antenna connector for connection of the supplied antenna or another antenna of choice.
Numerous other modules are also available for the MAC integrated motors. Plug-in expansion modules are used to adapt the motor to the application. Customers can choose the type of connector (D-Sub, cable terminals or watertight M12 connectors) and can freely choose between Profibus, DeviceNet, CANopen or Nano PLC control. High-speed and wireless modules provide even more possibilities. In this way, customers are claimed to have a level of flexibility and opportunities that are not provided by any other motors on the market, and they only need pay for the features required. In addition, JVL can develop special, customised modules to meet customer requirements.
